Methods for production of a bioproduct with a microorganism and selective extraction of bioproducts from a fermentation broth. The methods may include mixing a carbon source, a nitrogen source, and an extractant-depleted raffinate to form a fermentation medium, and fermenting the medium with a microorganism to form a fermentation broth having at least one bioproduct. The bioproduct may be extracted from the fermentation broth with an extractant comprising an olefin to form an extract and a raffinate, and the extract may be further separated from the raffinate. The bioproduct may then be separated from the extract, and the extractant may be separated from the raffinate to regenerate the extract-depleted raffinate.

A process is provided for bioconversion of carbon monoxide and carbon dioxide. More specifically, the process includes fermenting carbon monoxide and carbon dioxide containing substrate with acetogenic bacteria. The process provides for high levels of carbon monoxide and carbon dioxide conversions and utilization of hydrogen.

A process is described for producing BTX and alcohols from biomass, by a) catalytic pyrolysis of the biomass in a fluidized-bed reactor producing a gaseous pyrolysis effluent; b) separation of said gaseous pyrolysis effluent into at least one BTX fraction and a gaseous effluent containing at least carbon monoxide and carbon dioxide, c) sending all of the gaseous effluent from separation b) into fermentation producing a liquid fermentation stream containing at least one stream containing at least one oxygenated compound chosen from alcohols, diols, acid alcohols, carboxylic acids, aldehydes, ketones and esters, d) separating the fermentation stream obtained on conclusion of c) into at least the stream containing at least one oxygenated compound, an aqueous fraction, and an unreacted gaseous effluent, e) recycling at least part of unreacted gaseous effluent into the catalytic pyrolysis a).
